My patient’s name is Ruby
She is 73, is in a lot of pain and needs a new hip joint
She has diabetes and high blood pressure
I’ve told her about the surgery
She asked “Will I need a blood transfusion?”
I said “I’m glad you asked that”
“Here is the story about how we will look after you to give you
the best care and it’s called
Perioperative Patient Blood Management”
…….The Waiting List becomes the
Preoperative Preparation Period
Patient Blood Management (PBM)
Program
Implementation of a PBM Program
•
•
•
•
Develop a collaborative multidisciplinary program
Identify and manage preoperative anaemia
Manage anticoagulant and antiplatelet medication
Adopt multiple intraoperative strategies to minimise
blood loss
• Tolerance of postoperative anaemia
Perioperative Patient Blood Management
• Preoperative anemia assessment and management
• Intraoperative blood conservation including red blood
cell salvage
• Postoperative tolerance of anaemia (by transfusion
decision support)
Preoperative
Preoperative anaemia assessment
Preoperative haemoglobin assessment and optimisation template
This template1 is for patients undergoing procedures in which substantial blood loss is anticipated such as cardiac surgery, major orthopaedic, vascular
and general surgery. Specific details, including reference ranges and therapies, may need adaptation for local needs, expertise or patient groups.
Preoperative tests
• Full blood count
• Iron studies2 including ferritin
• CRP and renal function
Is the patient anaemic?
Hb <130 g/L (male) or
Hb <120 g/L (female)
NO
YES
Ferritin <30 mcg/L2,3
Ferritin 30–100 mcg/L2,3
Ferritin >100 mcg/L
CRP4
Raised
No anaemia: ferritin
<100 mcg/L
•Consider iron therapy# if
anticipated postoperative Hb
decrease is ≥30 g/L
•Determine cause and need for GI
investigations if ferritin is
suggestive of iron deficiency <30
mcg/L2,3
Iron deficiency anaemia
• Evaluate possible causes based
on clinical findings
• Discuss with gastroenterologist
regarding GI investigations and
their timing in relation to surgery3
• Commence iron therapy#
Normal
Possible iron deficiency
• Consider clinical context
• Consider haematology advice or,
in the presence of chronic kidney
disease, renal advice
• Discuss with gastroenterologist
regarding GI investigations and
their timing in relation to surgery3
• Commence iron therapy#
Possible anaemia of chronic
disease or inflammation, or
other cause5
• Consider clinical context
• Review renal function,
MCV/MCH and blood film
• Check B12/folate levels and
reticulocyte count
• Check liver and thyroid function
• Seek haematology advice or, in
the presence of chronic kidney
disease, renal advice
Preoperative anaemia management
Intraoperative
Intraoperative Techniques
to reduce blood loss
Intraoperative blood salvage
• collection of blood from
clean operative field
• automated cell saver
device / Sangvia
– suction salvaged
– washed
– concentrated
– resuspended
– Reinfused
Techniques to minimise surgical blood loss : “white
linen surgery”
• careful planning of actual surgical procedure, taking
account of blood conservation
• vascular conserving anatomical operative approaches
• minimally invasive surgery
• limb exsanguination before the application of a
tourniquet with Esmarch technique
• use of a surgical tourniquet at correct limb occlusion
pressure to enable surgeons to work in a bloodless
operative field (250 mmHg)
• Electrosurgical diathermy and harmonic scalpel
techniques (e.g. argon beam, cavitational ultrasonic
surgical aspirator [CUSA])
• Use of topical agents (e.g. thrombin, collagen, fibrin
glue, tranexamic acid)
“treat every patient as if they were a Jehovah’s
Witness”
Tranexamic acid (intravenous)
Hip Arthroplasty
15 mg/kg at induction
(? repeat dose at 8 and 16 hrs postoperatively)
Knee Arthroplasty
15 mg/kg prior to tourniquet release
(? repeat dose at 8 and 16 hrs postoperatively)
Cardiac surgery
15 mg/kg at induction, infusion of 4.5 mg/kg/hr intraoperatively
(higher doses have been associated with seizures)
Postoperative
Postoperative transfusion decision
support
Educate all clinicians about
THE THREE PILLARS:
“Optimise” preoperative red cell mass
“Minimise” perioperative blood loss
“Optimise” tolerance of postoperative anaemia
